# HTTX27600TJD

**HCI** · Crystals · SMD3225-4P

HTTX27600TJD from HCI, in a SMD3225-4P. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CRYSTAL_1 | passive | Crystal terminal 1 of the AT-cut fundamental crystal (8.000~60.000MHz, load capacitance 6~32pF or series, drive level 100µW typ / 300µW max). |
| 2 | NC_GND | passive | N.C. or GND; connected to the metal lid, may be left open (floating) or connected to ground. |
| 3 | CRYSTAL_2 | passive | Crystal terminal 2 of the AT-cut fundamental crystal (8.000~60.000MHz, load capacitance 6~32pF or series, drive level 100µW typ / 300µW max). |
| 4 | NC_GND | passive | N.C. or GND; connected to the metal lid, may be left open (floating) or connected to ground. |

## CAD (KiCad official)

- Symbol: `HTTX27600TJD`
- Footprint: `Crystal:Crystal_SMD_3225-4Pin_3.2x2.5mm`
- 3D model: SMD3225-4P (KiCad packages3D, STEP)
- 3D model files: `httx27600tjd-etched.step` / `httx27600tjd-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `httx27600tjd.step` / `httx27600tjd.glb` are the bare package body.
